Diploma

Yes, I think you are eligible, but remember don't be too late, otherwise, the dates will expire.

There isn't any reputed institute for MBA or Diploma in aviation, rather go for a core MBA from a tier 1 institute. Still, if you want to opt aviation only then prefer MBA over a diploma.

Branches like Mechanical, civil, electrical, computer science are the basic and always better.
